The human body is a complex organism that undergoes numerous physical and chemical changes each and every day. While complex in its processes, the makeup of the average human diet is quite simple. According to the National Academy of Sciences Institute of Medicine’s Food and Nutrition Board, the human diet should be made up of 40-65 percent carbohydrates, 20-35 percent fats, and 10-35 percent protein (Food and Nutrition Board). Protein is an extremely important macronutrient, not only because it is an important building block in your body and is found in every cell, but because it helps repair your damaged muscles and keeps your body healthy. For athletes, protein plays a vital role in muscle building, so obviously they will be more protein rather than less.
